AUTOMOBILE-WHEEL.

Specification of Letters Patent.

A atented July i6, 1918.

Application iled September 1S, 1917. Serial No. 191,302.

at Arcadia, in the county of Los Angeles and State of California, haveinvented new and useful Improvements in Automobile-VVheels, of which thefollowing is a speciiication.

This invention-relates to a vehicle wheel construction.

The principal object of this invention is to provide a wheel forvehicles which is so constructed as to prevent road shock from beingtransmitted through the spokes to the axles of the vehicle, thus takingconsiderable vibrating strain from the vehicle body.

Another object of this invention is to provide a vehicle wheel of an allmetal construction, the parts of which may be easilyV manufactured andreadily assembled.

Other objects will appear hereinafter.

The invention is illustrated, by way of example, in the accompanyingdrawings in which:

Figure l is a view in side elevation illustrating the vehicle wheel withwhich the present invention is concerned, with parts broken away toclearly show its construction.

Fig. 2 is a view in transverse section as seen on the line 2-2 of Fig.1, further disclosing the correlation of the various elements.

Fig. 3 is a fragmentary view drawn on an enlarged scale illustrating thespoke and reinforcing stay connection to the rim of the wheel. Y

Referring more particularly to the drawings, 10 in 'Cates a vehicle axleupon which are here shown roller bearings 11 and 12. Mounted upon thesebearings is a hub casting 13 within the opposite ends of which thebearings are seated. This casting is formed with an enlarged centralportion and parallel spaced flanges 14 and 15 against the outer faces ofwhich wheel side disks 16 and 17 bear. Circular bolting flanges 18 and19 are secured to the hub and are held in sliding relation to the sidedisks by means of clamping bolts 20. The flanges upon the hub and thebolting flanges are of the same di-V ameter and are held in spacedrelation to each other by shoulders on the hub which form circular slots21 and 22 within which the disks are positioned. lt will be understoodthat the side disks 16 and 17 are formed with bores through which thehub extends. .These bores are of larger diameter than the diameter ofthe'liub and permit a latitude of movement between the disks and thehub. Y

Disposed around the outer peripheries of the disks and therebetween is apressed metal telly 23 to which the disks are'iirinly bolted by bolts24.A This felly is designed to receive a tire riin 25 upon which ismounted a cushion tire 26.

Formed at intervals' around the inner periphery of the wheel telly areinwardly eX- tending ears 27 to which spokes are fastened.l As hereshown, there are `four pairs of these ears accommodating spokes 28, 29,30 and 31. The spokes are formed of cable having fittings 32 and 33 attheir opposite ends. Each of. the fittings 32 is secured between a pairof ears by a pin 34 while the fitting 33 upon the opposite end of eachspoke is mounted upon one of the bolts 20 by which the langes of the hubare secured in place. Pins -35 also extend through the ears to receivethe ends of stays 36 which are arranged diagonally from ear to ear.

The spokes are all of the saine length but are of a greater length thanthe normal radial distance between the bolts 20 and the pins 34. Due tothis arrangement the center of the hub will at all times be below thecenter of the telly, thus holding the uppermost of the spokes taut andthe iowermost loose.

in operation, the wheel is assembled as shown in the drawings and ttedwith a suitable cushion tire, after which it may be mounted upon avehicle and used. When the wheels are resting upon the ground and thespokes are in the position shown in Fig. l of the drawings, the weightcarried by the axle will be directly suspended upon the spoke 29 andheld centrally by the spokes 2S and 30. In case of a shock upon thewheel the axle may momentarily remain stationary to permit the wheel toslide in relation to its hub, this being allowed by the excessive' ieshave a floating movement independent of the rim.

twill thus be seen that .by Vthe use of this device the greater part ofthe road shock delivered to the rim will be lost and that an easy ridingwheel will be produced.

While l have shown the preferred construction of my automobile Wheel asnow.

known to me, it will be understood that various changes in thecombination, construction and arrangement of parts maybe made by thoseskilled in the art without departing from the spirit of my invention asclaimed.

I claim Y An automobile wheel comprising the combination with an axlehaving roller bearings1 of a hub mounted upon the bearings; said hubhaving an enlarged central portion and rigid parallel spaced angesextending outwardly around the central portion; circular bolting flangessecured to the hub and aced from the rigid flanges, wheel side disksslidingly mounted betweenV the bolting` iianges Y and rigid ianges; saidside disksV having Central bores through which the hub extends WILLIAMM.,SULLIVN,
